 1. Field of the Invention
 The present invention relates in general to an electronic note pad, and more particularly, to an electronic note pad of which a liquid crystal display panel has a dimension ranged between about 100 mm×140 mm and about 190 mm×260 mm.
 2. Description of the Related Art
 Currently, electronic note pads have not yet been seen in the market. Thus far, the personal digital assistant (PDA) is the only product that provides similar functions. However, as the liquid crystal display (LCD) panel of the personal digital assistant is very small, the personal digital assistant cannot be used as a note pad for inputting or writing data. For example, during a class or a meeting, users such as students, secretaries, and staff can hardly use a personal digital assistant for writing data or making notes.
 The invention provides an electronic note pad. The user can write or input data on any position on a touch panel, and the written data, including a character thereof, can be stored in an apparatus in a computer host of the electronic note pad. The electronic note pad has a dimension of 100 mm×140 mm to 190 mm×260 mm, so that the user can easily write data therein. The inconvenience in data writing for the personal data assistant is thus resolved.
 The invention provides an electronic note pad, on which data can be written or input directly. The electronic note pad comprises a liquid crystal display panel, a touch panel, a computer host, an application software package, and a wrist slider. The liquid crystal display panel uses liquid crystal to display data. The dimension, that is, the length by width, of the liquid crystal display panel is between about 100 mm×140 mm and about 190 mm×260 mm. The touch panel is connected to the liquid crystal display panel, and the available functions displayed thereon can be selected by touch control. Further, data can be written or input on the touch panel directly. The computer host is connected to the liquid crystal display panel and comprises a microprocessor for processing data and a storage apparatus connected to the microprocessor for storing data. The application software package is stored in the computer host to identify and store the data. The wrist slider connected to the touch panel can slide up and down to avoid the user mistakenly touching the touch panel, so as to result in an error of the data recognized by the application software package.
 In one embodiment of the invention, the data can be stored in the storage apparatus in a form of a written character. The application software package identifies the data from the top of the touch panel to the bottom of the touch panel. The color of the data can be changed to elicit the identification thereof.
 In one embodiment of the invention, a graph can be made on the electronic note pad and stored in the storage apparatus. The application software package performs the identifying process of the graph from the top of the touch panel to the bottom of the touch panel. The color of the graph can be changed to increase the ease of identification of the graph.
 The storage apparatus includes a memory card. The wrist slider can be restored by winding. The application software package is operated under the operating system of the computer host.
 In one embodiment of the invention, the computer host further comprises a recording apparatus to execute the recording function.
 In one embodiment of the invention, the computer host further comprises an infrared transmission apparatus, such that the data is transmitted using infrared transmission. Further, the data stored in the computer can be downloaded to the electronic note pad.
 The electronic note pad can also be used as an electronic dictionary, and a calculator for executing various kinds of conversion.
 Accordingly, the user can write or input data at any position on the touch panel. By the application software package, the data can be identified. The character written by the user can be stored in the storage apparatus. As the liquid crystal display panel has a dimension of 100 mm×140 mm to 190 mm×260 mm, which is much larger than that of the personal data assistant, it is easily for the user to write with. Therefore, the electronic note pad provided by the invention is writing friendly and has versatile functions.
 Both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
 Referring to
 The liquid crystal display panel
 The touch panel
 The wrist slider
 The computer host
 The application software package is stored in the computer host
 In addition, when the data or graph is input in the electronic note pad
 According to the above, the user can write or input data at any position of the touch panel. Further, the data can be identified using the application software package and stored in the storage apparatus of the computer host. The liquid crystal display panel has a length by width of about 100 mm×140 mm to about 190 mm×260 mm. The area is much larger than the display panel in the personal data assistant. It is thus more convenient for the user to write. Thus, the invention provides an electronic note pad which is suitable for handwriting and has versatile functions.
 Accordingly, the invention has the following advantages:
 1. A larger area of liquid crystal display panel compared to personal data assistant, such that the user can easily write data thereon; and
 2. Full functions.
 Other embodiments of the invention will appear to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples are to be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.
